Firefox add-on that tracks webpage load time including DNS retrieve time?

Firefox add-on that tracks webpage load time including DNS retrieve time? I used to have this add-on but now I forgot what it's called. Basically it can track any website's load time, DNS seeking time, time from host to javascript execution and HTML rendering, things like that.

"Firebug's ""Net"" panel does this. It gives you timing info for the following:

DNS lookup
Connecting
Queueing
Waiting for response
Receiving data
When the DOMContentLoaded event fires
When the load event fires"
